What does code F51 tell me

On model wtw6600sw2 washer I am receiving a code of f51, what does it mean?

Rasman,

That failure code is indicating:

The control board is not seeing the proper motor rotations.

The checks and repairs are somewhat easy to perform.

A) Check and make sure there is nothing stuck between the tubs.
(you may have to raise the top of the machine and remove the tub cover
from the tubs to check).

B) Check the wire harness that tails down the right rear corner of the
cabinet and down to the motor, for loose connections or damage, and up
to the main control board.

If all checks are satisfactory,

You will need to replace the motor “RPS” and harness(kit).

But as I stated, check between the tubs first, something as small as a baby sock can cause that tub to slow spin and an overlaod in the wash cycle will do the same.

Good Luck,
:cool: :cool: :cool:
